Product Details

A whetstone is considered by many chefs (and us!) to be the best way to sharpen a knife, as it sheds the least amount of metal from a knife while respecting the shape of the blade. Made of hard ceramics, this Japanese-made stone ensures speedy results and does not wear out easily. This is especially important for Japanese knives, which have tapered V-shaped edges. This Kai Seki Magoroku Combination Whetstone has a coarse 1000 grit for sharpening dull knives and a very fine 4000 grit on the other side for honing the edge. With this high grit, your knife may even be sharper than when it was new. The whetstone comes in a protective sleeve with its base providing stability while using.

Why we love it

'If you want your knives to last the longest they can, while performing in top condition, use a whetstone.'

About The Brand


Since its founding in 1908, Kai knives have held a cult status in Japan—and since their European debut in 1980, the rest of the world has caught on. Taking their inspiration from samurai blacksmithing but incorporating modern manufacturing processes, Kai has mastered the art of making extremely sharp, durable knives that feel effortless to use. All their knives are manufactured in Seki, the knife capital of Japan. As their products reached global popularity, Kai has expanded their range to include European shapes like the chef’s knife as well as ambidextrous handles, such as in the Kai Shun Premier and Kai Shun Nagare ranges.
